Girls and sons who have not been loved by their fathers seek attention once teens and adults to compensate for what they didnt have originally. They are extremistic and have troubles adapting to society's rules, because they also have troubles defining their own identity and respecting authority and hierarchy.
Also boys who got picked on by others during childhood and adolescence -often sons without a father figure- try to compensate by lifting weights, to develop muscles and survive in ther male world. They re insecure because they re girly, childish, having been raised by a single mom. They lift obsessively hoping it will transform them into men, to compensate for their lack of influence from a father figure that was not there. Unfortunaltey they can get as big as they can it doesnt cure their insecurity and who they truly are, how they grew up being raised by a single mom. They re no as manly as other men whatever they do, and they often have a big lack of masculine presence, hence often being borderline homosexuals. They are often the ones that, in order to get respect from other males will go the steroids route to get even "bigger" attemptint to cure their insecurity. The lack of a father figure also often means they didnt have guidance to continue studies and are often working shitty manual jobs.
